After placing a new Image on my Wife’s system I then installed the usual software and made a Snapshot, froze that. However, now if I place something on the desktop and reboot, the item/folder is still there.

So hence the title; "What have I done wrong?".

Although this seems unlikely, I'll go ahead and ask what is, to me, the obvious question: Have you perhaps "anchored" the desktop folder or one of it's parents/"ancestors" ?

That screen looks very normal and the blue star indicates a FROZEN snapshot and there is only ONE blue star possible.
The green arrow indicates that it's the ACTIVE snapshot and there is only ONE green arrow possible.
The slightest change in that snapshot will be undone during the next reboot.

I just created a frozen snapshot and drag an dropped the folder "My Music" on my desktop, which created an icon "My Music" on my desktop
I rebooted in the frozen snapshot and the icon "My Music" was gone, which means that the frozen snapshot works.

If your computer boots in a frozen snapshot the "Welcome" screen is displayed alot longer than you boot in a normal snapshot.
So this is an indication to see that the frozen snapshot works.
You also have to check that the "Freeze Storage.arx" has been created.
You can create your own folder and file-name for the freeze storage when you click on Tools / Options / Freeze.
This way you can move the freeze storage to another partition in order to save space on your system partition [C:]

Yes THAT IS THE REASON why the freezing doesn't work.
I've tested this and the icon "My Music" was still there.
I wonder why the Pre-boot was disabled, I never disable/enable the Preboot screen for any reason.
